Biotech in CDR - Reginato
Paul Reginato explains how biotech can be applied to CDR. Paper: Biotechnology in direct air capture, enhanced weathering, and methane removal: emerging opportunities and gaps. https://doi.org/10.3389/fclim.2024.1440833
Reviewer 2 quibbles with actual experts in Solar Radiation Modification and Carbon Dioxide Removal, before rejecting their work on spurious, spiteful and capricious grounds. You'd expect nothing less from R2.
